Eugene Chornyi aaca6b24f1 Fix bug 9961
remove the error message for not finding a pdf viewer (apparently empty string is returned by FindExecutable if the executable is a Windows Store app). If there is really no pdf viewer, let the Windows itself decide what to do (produce error or not and which one).

/*
Windows PDF view helper
Author: Uwe Stöhr and Joost Verburg
This will be installed as pdfview.exe.
The application will launch the default PDF viewer to display the PDF file,
but works around the file locking problems of Adobe Reader and Acrobat.
